Since the murder of Glasgow shopkeeper Asad Shah last month, there has been a focus on the Ahmadiyya Muslim community of which he was a member. Zoe Conway reports from an Ahmadi mosque in Glasgow and Mark Hamilton, Hate Crime lead for the NPCC and Rafiq Hayat, leader of the Ahmadiyya community in the UK, discuss what needs to be done to tackle hate crime and religious prejudice.
